Concurrent Transaction

There are many techniques in the recent years that provide the synchronization among the transactions using shared data like 2 phase locking protocol and time stamping in distributed database system. These techniques are efficient and provide fast transactional operations and serializable execution of the transactions. But these existing techniques like 2PL abort the transaction when a conflict occurs in transaction actions that result in degradation in the performance. In this dissertation we analyse the purposed techniques that provide the serial execution of the concurrent transactions. To achieve the serializability among the transactions in the distributed database Conflict serializability model is used that will provide serial execution of the transactions with in conflict actions of the transactions. The objectives of the scheme are achieved that provide the better performance than the existing 2PL schemes and achieve the consistency among the concurrent transaction execution. Performance is evaluated of CS model against the 2PL model in distributed database to sustain the synchronization in the transactions. Results illustrate that the proposed new scheme increase the performance by decreasing the abort rate in distributed environment.

Distributed Database Management

Distributed database management systems manage a huge amount of data as well as large and increasingly growing number of users through different types of queries. Therefore, efficient methods for accessing these data volumes will be required to provide a high and an acceptable level of system performance.  Data in these systems are varying in terms of types from texts to images, audios and videos that must be available through an optimized level of replication. Distributed database systems have many parameters like data distribution degree, operation mode and the number of sites and replication. These parameters have played a major role in any performance evaluation study. This paper investigates the main parameters that may affect the system performance, which may help with configuring the distributed database system for enhancing the overall system performance.
